HUHUTECH designs and installs specialized infrastructure systems for semiconductor fabs and electronics manufacturers, primarily in China. The company's two core product lines are High-Purity Process Systems (HPS) and Factory Management and Control Systems (FMCS). HPS covers the physical delivery of ultra-clean gases and chemicals from storage to manufacturing equipment inside a fab — including gas cabinets, valve manifold boxes, piping, and monitoring software — and currently generates the majority of revenue. FMCS is a software and hardware platform that integrates monitoring of all facility systems (gas, chemicals, power, water, HVAC, and others) into a single control room interface. HUHUTECH also sells standalone sub-systems to customers who don't need the full integrated platform. The company operates as a project-based engineering and systems integrator: customers issue bids for new production lines or upgrades, HUHUTECH proposes and, if selected, designs, procures, and installs the system. Revenue is recognized on project completion, with payments structured across the project lifecycle and a 3–5% warranty holdback retained for one to two years. Cost of revenue is driven by procured components — PLCs, valves, pipes, and sensors — plus installation labor. Customer concentration is moderate, with the largest customer accounting for roughly 26% of revenue in FY2025. HUHUTECH operates primarily in China but has established subsidiaries in Japan, Germany, the U.S., and Singapore, with the Japan presence focused on the semiconductor cluster around the TSMC Kumamoto fab.
